Abstract: A wireless access point that serves one or more wireless client devices in a wireless network determines that at least one particular client device that is associated to the wireless access point should not be associated to the wireless access point. The wireless access point transmits frames so that they are received at the particular client device with reduced strength so as to provoke the particular client device to transition from the wireless access point.

Abstract: An access point (AP) transmits Wi-Fi transmit frames according to a Wi-Fi protocol and Long-Term Evolution-Unlicensed (LTE-U) transmit frames according to an LTE-U protocol in a shared channel bandwidth that encompasses unlicensed channel bandwidth associated with the LTE-U protocol. The AP assigns a Wi-Fi access category to each Wi-Fi transmit frame and assigns to each LTE-U transmit frame an LTE-U access category. The AP schedules Wi-Fi and LTE-U transmit opportunities for the Wi-Fi transmit frames and the LTE-U transmit frames, respectively, in the shared channel bandwidth based on the Wi-Fi and LTE-U access categories. The scheduling includes, for each scheduled LTE-U transmit opportunity: constructing a Wi-Fi quiet message commanding Wi-Fi clients of the AP not to transmit in the shared channel bandwidth during the LTE-U transmit opportunity; and scheduling the Wi-Fi quiet message for transmission to the Wi-Fi clients.

Abstract: A wireless access point (AP) configured to operate in accordance with both Wi-Fi and Long-Term Evolution (LTE-U) standards/protocols jointly schedules transmit opportunities for Wi-Fi and LTE-U frames. The AP assigns one of multiple, prioritized, Wi-Fi access categories to each Wi-Fi transmit frame based on a type of data in the transmit frame. The AP also assigns to each LTE-U transmit frame an LTE-U access category prioritized relative to the Wi-Fi access categories. The AP schedules Wi-Fi and LTE-U transmit opportunities for the Wi-Fi transmit frames and the LTE-U transmit frames, respectively, in the shared channel bandwidth based on the prioritized Wi-Fi and LTE-U access categories.

Abstract: A Long-Term Evolution-Unlicensed (LTE-U) access point (AP) is configured to operate wirelessly on any of multiple RF channels in an unlicensed frequency band. The AP detects other LTE-U APs and Wi-Fi APs operating on active ones of the multiple channels. The AP determines AP channel statistics for each detected AP. The AP determines, for each active channel, a per-channel metric based on the AP channel statistics. The AP ranks the active channels according to the corresponding per-channel metrics, and selects a best channel on which to transmit in the unlicensed frequency band from among the ranked active channels based on the rankings.

Abstract: Presented herein are techniques for using uplink transmissions from devices (e.g., wireless tags, clients, etc.) to determine a path loss between neighboring access points. In one example, a wireless controller obtains receive signal strength information of uplink transmissions received at neighboring access points in a wireless network. The wireless controller determines an effective path loss between the neighboring access points based on the receive signal strength information for the uplink transmissions received at the neighboring access points. The wireless controller also performs radio resource management operations in the wireless network using the effective path loss determined based on the uplink transmissions received at the neighboring access points.

Abstract: Techniques are presented herein for providing hybrid contention mechanisms for a wireless medium. A first wireless device (e.g., a wireless access point) that serves a plurality of second wireless devices (e.g., client devices) in a wireless network, groups the plurality of second wireless devices into sets based on commonality of the second wireless devices in terms of one or more of: power requirements and throughput requirements. A time interval on a wireless channel during which the second wireless devices may contend for usage of the wireless medium is partitioned into a plurality of disjoint or overlapping contention periods. Each set of second wireless devices is assigned to a corresponding one of the plurality of contention periods such that only second wireless devices in each set contend for access to the wireless channel during the corresponding contention period assigned to that set.

Abstract: Techniques are provided to determine whether or not incident power at a wireless communication device in at least two frequency channels is from the same device. Incident power in frequency channels allocated to a basic service set in a wireless network is received at a plurality of antennas of the wireless communication device. Channel state information is computed for at least two frequency channels allocated to the basic service set. One or more metrics are generated based on the channel state information in the two frequency channels. The one or more metrics are evaluated to characterize an uplink signal bandwidth associated with the two channels to determine whether or not the incident power in the two channels is from the same device.

Abstract: Techniques are provided for selecting channels for use by access points operating in a wireless local area network. Metrics are computed for at least one set of radio frequency (RF) channels, wherein the set of RF channels comprises at least two RF channels in a frequency band that are available for use by a wireless network for a wider bandwidth mode that combines bandwidth of two or more RF channels. Alignment of individual primary and secondary RF channels is determined in the set of RF channels for operation of at least first and second wireless networks. A bias is applied to the metrics for each RF channel that is a member of the set of RF channels for the primary channel depending on alignment of the primary and secondary channels of the respective first and second wireless networks to produce adjusted metrics, based on which RF channels are assigned.

Abstract: Techniques are provided to compute downlink beamforming weights for beamforming multiple spatial streams to a wireless device when that wireless device does not transmit with a maximum number of spatial streams, and thus when the full dimensional knowledge of the wireless channel to that wireless device needs to be implicitly derived. Uplink signals are received at a plurality of antennas of a first wireless device that are transmitted via a plurality of antennas of a second wireless device. The first wireless device derives values at a plurality of subcarriers of the received signals across the plurality of antennas of the first wireless device. Downlink beamforming weights are computed from values of consecutive subcarriers across the plurality of antennas of the first wireless device. The first wireless device applies the downlink beamforming weights at respective subcarriers to a number of spatial streams to be transmitted to the second wireless device.
